Muwatta Malik #350
Shortening the Prayer
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ أَبِيهِ، عَنْ عُمَرَ بْنِ الْخَطَّابِ، مِثْلَ ذَلِكَ .
Yahya related the same as that to me from Malik from Zayd ibn Aslam from his father from Umar ibn al-Khattab.
